The following points must be checked or adapted for each measurement:
 Define the parameters of the calculation methods (see §4.5).
 Select the distribution system (single-phase to four-wire three-phase) and the connection method (2 wattmeters, standard)
(see §4.6).
 Program the current ratios according to the type of current sensor connected (see §4.7).
 Program the voltage ratios (see §4.7).
 Define the triggering levels (transients mode) (see §4.8) (for the C.A. 8333 only).
 Define the values to be recorded (trend mode) (see §4.9).
 Define the alarm thresholds (see §4.10) (for the C.A. 8333 only).
To return to the Configuration screen from a sub-menu, press the key.
3.3. INSTALLATION OF LEADS
To identify the leads and input terminals, you may mark them in accordance with the usual phase/neutral colour code using the
coloured rings and inserts supplied with the device.
 Detach the insert and place it in the hole provided for it near the terminal (large insert for a current terminal; small insert for a
voltage terminal).

Figure 10: Identification of the leads and terminals
 Clip rings of the same colour to the ends of the lead you will be connecting to the terminal.
Twelve sets of rings and inserts of different colours are provided to enable you to harmonize the device with any of the phase/
neutral colour codes in force.
 Connect the measurement leads to the terminals of the device:
Large insert for
current terminal.
Small insert for
voltage terminal.
Rings the same colour as
the terminal.
3 current inputs terminals.
4 voltage input terminals.

 Remember to define the transformation ratios of the current sensors and of the voltage inputs (see §4.7).
